PRICING SUPPLEMENT No. 2, dated November 17, 2023

(To prospectus, dated September 22, 2023, and prospectus

supplement, dated September 22, 2023)

Senior Medium-Term Notes, Series A

Due 9 Months or More from Date of Issue

This pricing supplement supplements the terms and conditions in the prospectus, dated September 22, 2023 (the “base prospectus), as supplemented by the prospectus supplement, dated September 22, 2023 (the “prospectus supplement” and together with the base prospectus, and all documents incorporated herein by reference therein and herein, the “prospectus”), and describes our senior notes that will be issued in a reopening under our Senior Medium Term Note Program, Series A. The notes to be issued in the reopening (the “Notes”) will have the same terms as, and constitute a single series with, the $750,000,000 aggregate principal amount of 7.413% Fixed Rate/Floating Rate Senior Notes due October 30, 2029, issued on October 30, 2023 (the “Original Notes”). The Notes will have the same CUSIP number as the Original Notes and will trade interchangeably with the Original Notes immediately upon settlement. As a result, the outstanding aggregate principal amount of our 7.413% Fixed Rate/Floating Rate Senior Notes due October 30, 2029 as of the expected issue date of the Notes will be $1,000,000,000 . The Notes mature on October 30, 2029. Unless otherwise defined in this pricing supplement, terms used herein have the same meanings as are given to them in the prospectus.

The Notes are unsecured. The Notes will rank equally with all of our other unsecured and unsubordinated indebtedness that is not accorded a priority under applicable law.

The Notes are not savings accounts, deposits or other obligations of any of our bank or non-bank subsidiaries and are not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency.

Investing in the Notes involves risk. See “Risk Factors” beginning on page S-7 of the prospectus supplement and the discussion of risk factors contained in our annual, quarterly and current reports filed with the Securities and Exchange Commission (the “SEC”) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which are incorporated herein by reference.

None of the Securities and Exchange Commission (the “SEC”), any state securities commission, the New York State Department of Financial Services or the Board of Governors of the Federal Reserve System or any other governmental agency has approved or disapproved of the Notes passed upon the adequacy or accuracy of this pricing supplement, the attached prospectus supplement or the attached prospectus. Any representation to the contrary is a criminal offense.

We expect to deliver the Notes to investors through the book-entry delivery system of The Depository Trust Company and its direct participants on or about November 21, 2023.

USE OF PROCEEDS

We will use the net proceeds from the sale of the Notes for general corporate purposes, including investments in and advances to our bank and nonbank subsidiaries, reduction of outstanding borrowings or indebtedness, short and long-term investments and financing possible future acquisitions including, without limitation, the acquisition of banking and nonbanking companies and financial assets and liabilities. All or a portion of the net proceeds from the sale of Notes may also be used to finance, in whole or in part, our repurchase of common shares pursuant to any share repurchase program securities repurchases undertaken from time to time. The precise amounts and timing of the application of proceeds will vary with liquidity and funding requirements.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The Company believes that the Notes should be treated as variable rate Notes that are not issued with original issue discount for United States federal income tax purposes. See the discussion in the prospectus supplement under “Certain United States Federal Income Tax Considerations” for a discussion of the United States federal income tax consequences of investing in the Notes.

We will treat the Notes being issued in this reopening as having been issued in a “qualified reopening” of the Original Notes. For U.S. federal income tax purposes, debt instruments issued in a qualified reopening are deemed to be part of the same issue as the original debt instruments. Accordingly, we will treat the Notes as having the same issue date and issue price as the Original Notes and as being fungible with the Original Notes for U.S. federal income tax purposes. Because the purchase price of the Notes exceeds the principal amount of the Notes, a United States holder may elect to treat the excess (after excluding the portion of the purchase price attributable to accrued interest) as amortizable bond premium, as discussed in the prospectus supplement under “Certain United States Federal Income Tax Considerations—U.S. Holders—Amortizable Bond Premium.”

A portion of the price paid for the Notes will be allocable to interest that accrued prior to their issue date (“pre-acquisition accrued interest”). On the first interest payment date with respect to the Notes, a U.S. Holder may treat a portion of the interest received, in an amount equal to the pre-acquisition accrued interest, as a return of the pre-acquisition accrued interest and not as a payment of interest on the Notes. Amounts treated as a return of pre-acquisition accrued interest should not be taxable when received. U.S. Holders should consult their own tax advisors concerning the treatment of the pre-acquisition accrued interest.
